.SPECIFXCATION forming part Of Letters Patent N0. 710,739, dated October7, 1902.

Application filed February 4, 1901. Serial No. 45,950. (No model.)

To @ZZ whom, t T11/(ty concern,.-

Be it known that I, CHARLES A. BARTLIFE, a citizen of the United States,residing at the citj7 of St. Louis, in the State of Missouri,haveinvented a certain new and useful Improvement in Apparatus forDrawingBeer,of which the following is a full, clear, and exact description,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,forming part of this specification, in which- Figure l is a'perspectiveview illustrating my improved system. Fig. 2 is a detail verticalsectional View showing one of the cooling-reservoirs. Fig. 3 is anelevational view of the top or cover of said reservoir. Fig. Li is abottom plan view of said. top or cover. Fig. 5 is atop plan view of thereservoir; and Fig. 6 is a sectional view through a coolingchamber,showing several cooling-reservoirs in position therein.

This invention relates to a new and useful improvement 'in a system ofdrawing beer, the object being to utilize a system of storagereservoirs,whereby the beer on draft maybe chilled or cooled in its passage fromthe keg to the spigot.

Vith these objects in view the invention consists in the construction,arrangement, and combination of the several parts, all as willhereinafter be described and afterward pointed out in the claims.

In the drawings, Fig. lshows myimproved system arranged in position, thekegs of beer or source of supply being in what we will designate as thecellar or lower compartment, having a pressure-reservoir connectedtherewith, while the pipes leading from said legs enter acooling-chamber containing a series of reservoirs from which the beer isdrawn.

A indicates the kegs or barrels containing the beer, from which leadpipes B to a cooling-chamber C. These pipes have appropriate cocks andmanually-operable connections, such as are usually employed. The pipe Bentering the cooling-chamber is connected to a reservoir D. There are aseries of these reservoirs in the coolingchamber, and as they arepractically identical in construction I will describe but one.

This reservoir is preferably made of glass in the form of a jar having athreaded neck for receiving a coupling-collar E. The side walls of thejar at the bottom are provided with projections d, designed to [it inrecesses in the bottom of the reservoir C, whereby when the jar is iuposition in said cooling-chamber it is prevented from being turned.

F indicates a cap or cover for the reservoir, which, cover is preferablymade as a casting, between which and the top of the reservoir isarranged a suitable gasket j' for well-understood purposes. Thecoupling-collarEis provided with an inturned Ilange at its upper edgeextending over the margin of the cap F, whereby when saidcoupling-collar is screwed home it clamps the cap in position and sealsthe reservoir. For ease of manipulation this coupling-collar ispreferably provided with handles e. Cap F is provided with ascrewthreaded bossf, upon which is received a coupling-collarf, saidcoupling-collarsecuring in position the end of the pipe B. A gasket isarranged between the end of pipe B and the bossf for well-understoodpurposes. f3 indicates a boss similar in all respects to the boss f,said boss f3 also receiving a coupling-collar f4, to whichcoupling-collar is secured a nipple fr', said nipple receiving atube f,which tube connects with the boss f' of the next adjacent reservoir. Thecap F is also provided with a nipple f7, substantially in alinement withthe boss f3, to which nipple f7 is secu red a glass tube f8 by means ofsome appropriate connection-as, for instance, a short sectionof rubbertube f. This glass tube fS extends to the bottom of the reservoir andforms part of the delivery-pipe from said reservoir. These reservoirsare connected together in series, the deliverypipe Yfrom one terminatingat the cap of the other, the. The delivery-pipe of the last reservoir inthe series connects with a spigot fw, extending outside thecooling-chamber, as shown in Fig. l. In order to prevent the cap F fromturning on the reservoir, I provide lugs d in the neck of the reservoir,which lugs fit in corresponding recessesin the under flange of the capF.

G indicates a reservoir preferably arranged in juxtaposition tothesource of beer-supply, which reservoir G is in the form of a tank ICOand contains compressed gas. From this tank leads a pipe g, preferablyprovided with a pressure-gage and suitable cocks, said pipe connectingwith a iitting through which said pipe B passes in its entrance into thekegs.

The operation of my improved system is as follows: The reservoirs beingconnected as shown and the beer admitted thereto, the beer will flowinto the reservoirs, practically llingthem. Thereservoirsbeingsurroundedby ice will enable the beer to be readily chilled or cooled, and as thebeer is drawn from the reservoir nearest the spigot a supply of freshcold beer immediately fiows into said reservoir from those reservoirsconnected therewith. It will be noticed that the intake-pipes of all thereservoirs terminate at the cap or cover, while the outlet-pipes startfrom the bottom of the reservoir. By this construction the liquid isallowed to iiow from one reservoir to the other, keeping all of themfilled as long as the supply of beer in the keg equals the demands uponthe spigot. However, when the beer is exhausted from the keg thepressure from the tank G is then exerted directly upon the surface ofthe beer in the last reservoir, forcing said beer out through thedischarge-pipe according to the demands upon the spigot, and when thebeer is exhausted from said last reservoir the pressure from the tank Gis direct upon the surface of the beer in the next reservoir. The tank Gis charged to a pressure of, say, one

thousand five hundred pounds to the square inch, which pressure isreduced by suitable means arranged in the length of pipe g andinterposed between said tank Gand the kegs to, say, five pounds pressureto the square inch. Hence it will be seen that the charge of gascontained in said tank G is sufficient to exhaust quite a large numberof kegs of their contents.

By constructing the reservoirs and their pipes of glass tubing wherepossible, thus reducing the iron surface which might contact with thebeer to the smallest area, I am enabled to keep the apparatus in acleanly condition with a minimum amount of labor. All

couplings, tbc., are preferably what is known as union-couplings, sothat they may be readily coupled and uncoupled.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The combination with a reservoir, of a removable cover for thereservoir comprising a cap F resting upon the upper edge of thereservoir, means for locking the cap against independent rotation,clamping means for holding the cap in place, inlet and outlet openingsin the cap, an outwardly-extending boss adjacent the inlet-openingadapted to be coupled with a suitable supply, a corresponding bossadjacent the outlet-opening adapted to be coupled with a suitabledischarge, a third boss extending inwardly from the cap in alinementwith the outlet, and a tube coupled to said third boss and projectingdownwardly to a point near the bottom of the reservoir, substantially asdescribed.

2. The combination with a receptacle, of a cap for closing the top ofthe same, means for preventing independent movement of said cap, agasket under said cap, a coupling-collar for clamping said cap on thegasket, threaded bosses projecting up from the cap, pipes detachablyconnected to said bosses, and a boss on the under side of the cap inline with one of the rst-mentioned bosses, and a pipe depending fromsaid downwardlyprojecting boss; substantially as described.

3. In combination substantially as described, a receptacle, a series ofreservoirs seated in said receptacle, removable caps fltting the mouthsof the reservoirs, rotary clamps movable independently of the caps forretaining the same in place, means for preventing independent rotationof the reservoirs in their seats, auxiliary means forpreventingindependent rotation of the caps relative to the reservoirs,inlets and outlets in the caps, communications betweenthe adjacent caps,and a source of supply and a discharge respectively coupled with the endreservoirs of the series,.substantially as described.

In testimony whereof I hereunto afx my signature, in the presence of twowitnesses, this 28th day of January, 1901.A
